599-1 Heterogeneous catalysis (M2R - C7) Materials and Chemistry S9
Lessons : 15 h TD : 0 h TP : 0 h Project : 0 h Total : 15 h
Co-ordinator : Jean-Pierre Gilson
Prerequisite
Thermodynamics and kinetic 2nd year engineering school
Course Objectives
A better appreciation of cutting-edge research in heterogeneous catalysis and its industrial applications.
Syllabus
Homogenous and heterogeneous catalysis: definitions; advantages and limitations of heterogeneous catalysis compared with homogeneous catalysis; how a catalyst in Heterogeneous Catalysis is acted; steps in the catalytic cycle adsorption and reaction.
Acid catalysis: definitions; specific acid catalysis and general acid Catalysis; heterogeneous acid catalysis, mode of action; the generation and detection of the acid sites of Brunsted and Lewis on the surface of the oxides; Hammett's acid function.
Acid oxides - structures and properties: classification of acid oxides; modified alumina, amorphous alumina silices; molecular sieves (zeoliths, ALPO and SAPO); pillar clays; ..). Generating the acidity of Brunsted; relationship with structure and activity.
Acid oxides - catalytic properties: types of catalysed reactions (alkylation; isomerization; oligomerization; addition and elimination; esterification
Practical work (TD or TP)
"Typical" questions will be distributed at the end of each chapter.
Acquired skills
Knowledge of the structural properties of different families of "acid" catalysts in relation to the genesis of acidity and catalytic performance.
